Sweeping Hands
Age 7 to 11 Challenge Level:
Use your knowledge of angles to work out how many degrees the hour and minute hands of a clock travel through in different amounts of time.
Take the Right Angle
Age 7 to 11 Challenge Level:
How many times in twelve hours do the hands of a clock form a right angle? Use the interactivity to check your answers.
Watch the Clock
Age 7 to 11 Challenge Level:
During the third hour after midnight the hands on a clock point in the same direction (so one hand is over the top of the other). At what time, to the nearest second, does this happen?
On Time
Age 11 to 14 Challenge Level:
On a clock the three hands - the second, minute and hour hands - are on the same axis. How often in a 24 hour day will the second hand be parallel to either of the two other hands?
Right Time
Age 11 to 14 Challenge Level:
At the time of writing the hour and minute hands of my clock are at right angles. How long will it be before they are at right angles again?
Six Places to Visit
Age 7 to 11 Challenge Level:
Can you describe the journey to each of the six places on these maps? How would you turn at each junction?
How Safe Are You?
Age 7 to 11 Challenge Level:
How much do you have to turn these dials by in order to unlock the safes?
Overlapping Squares
Age 7 to 11 Challenge Level:
Have a good look at these images. Can you describe what is happening? There are plenty more images like this on NRICH's Exploring Squares CD.
Clock Hands
Age 7 to 11 Challenge Level:
This investigation explores using different shapes as the hands of the clock. What things occur as the the hands move.

Age 5 to 11 Challenge Level:
Geometry problems at primary level that require careful consideration.
Olympic Turns
Age 7 to 11 Challenge Level:
This task looks at the different turns involved in different Olympic sports as a way of exploring the mathematics of turns and angles.
Dotty Circle
Age 7 to 11 Challenge Level:
Watch this film carefully. Can you find a general rule for explaining when the dot will be this same distance from the horizontal axis?
Subtended Angles
Age 11 to 14 Challenge Level:
What is the relationship between the angle at the centre and the angles at the circumference, for angles which stand on the same arc? Can you prove it?
LOGO Challenge 7 - More Stars and Squares
Age 11 to 16 Challenge Level:
Can you use LOGO to create a systematic reproduction of a basic design? An introduction to variables in a familiar setting.
Which Solids Can We Make?
Age 11 to 14 Challenge Level:
Interior angles can help us to work out which polygons will tessellate. Can we use similar ideas to predict which polygons combine to create semi-regular solids?
Maurits Cornelius Escher
Age 7 to 14
Have you ever noticed how mathematical ideas are often used in patterns that we see all around us? This article describes the life of Escher who was a passionate believer that maths and art can be. . . .

Age 11 to 14 Challenge Level:
Can you make a right-angled triangle on this peg-board by joining up three points round the edge?
Polygon Rings
Age 11 to 14 Challenge Level:
Join pentagons together edge to edge. Will they form a ring?
Semi-regular Tessellations
Age 11 to 16 Challenge Level:
Semi-regular tessellations combine two or more different regular polygons to fill the plane. Can you find all the semi-regular tessellations?
Witch's Hat
